I can live with SafeDisc.

I read City Life uses StarForce, but CL World Edition doesn't. I'm not sure about CL 2008 Edition, though. I think I'll steer clear of it though, just in case.
SC4 is the one I am actually after. Since SCS is a part of the collection, I would probably try it. I watched a video of Sim Carnival: Snap City. That is apart of the box collection also. Snap City looks really dorky. It's like a cross of SimCity and Tetris.
